About HKC


Marc Gieselmann with some of his crew members.

We are family owned and operated. The owner, Marc Gieselmann began in the construction business over 30 years ago. HK Construction incorporated in 1997. HKC has experience in all phases of home remodeling, and uses its own crews for most work. Our primary expertise is in room additions and loft construction. We also do other home expansion construction and remodeling such as kitchens, bathrooms, 2nd story additions, decks, and concrete work.

Operating Procedure

HKC employees an office manager and currently has 10 crew members, of which one is our production manager and another is a lead carpenter. During the course of the construction or home remodeling project, and according to the permitted plans, our crew performs the following:

  • demolition,
  • debris isolation,
  • construction debris removal,
  • digs and prepares foundations
  • supervises concrete pouring,
  • completes all aspects of the framing,
  • schedules all required inspections, and
  • completes all contracted finish work including final cleanup.

We order all building materials according to contract including custom size items such as windows and doors. We also schedule, oversee, and supervise all subcontractors relevant to the project (according to contract) such as, electrician, plumber, dry waller, insulation, stucco, painters, etc.

During the remodeling process, our project and/or production managers consistently inspect the project site, examine the plans and specifications of the project, and supervise their crew and subcontractors. All as stated in the contract.

Informational Procedure

HKC has procedures in place the keep the homeowner fully informed of the progress of their project. Such as:

  • Interfacing with the homeowner through the permitting process,
  • Check-off lists for items to purchase and decisions to make,
  • Notifying when required inspections are going to happen,
  • Informing the homeowner of progress payment schedules.

We provide timely invoicing according to the contractual payment schedule so our homeowners always know what has been paid for and/or when a payment is due. Our office manager sends homeowners a courtesy notice when we make a payment for the project’s material supplies and to the project’s subcontractors. Did you know this one informational procedure a rare thing in the construction home remodeling business? It’s true! We do this because we care.


HKC presents a clearly written proposal/contract with a set price for materials, labor, and project management. This includes specifications stating all work to be done and materials to be used. Based on our experience with the homeowner’s type of project, we designate a start and finish time.

Permit Process

At the homeowners request we will draw the plans for the city building department, determine if the project need structural engineering, and oversee the city building permitting process. At the pre-construction meeting with the homeowner we’ll go over all the workmen schedules and review the entire project. The intent making sure the homeowner has a full understanding of what they can expect as HKC moves through the project.

Safe and Clean

Work crews regularly maintain the job-site in a safe and clean condition. They secure the homeowner’s residence (or project site) upon vacating the job-site if homeowner is not present at the end of the day.


Satisfaction is guaranteed, meaning, no project is finished until all scheduled work within the scope of the contract is properly completed and to the homeowners satisfaction. HKC’s 5-year Warranty covers materials used and workmanship performed on the project, per the signed contract, for a period of 5 years from date of completion. It’s our sincere hope this shows our customers that we are in business for the long term building quality relationships rather than a short term “fly by night” scenario.
